apcu_delete — Removes a stored variable from the cache

### Beschreibung

apcu_delete(mixed `$key`): mixed

Removes a stored variable from the cache.

### Parameter-Liste

`key`
  A `key` used to store the value as a string for a single key, or as an array of strings for several keys, or as an APCUIterator object.

### Rückgabewerte

If `key` is an Array, an indexed Array of the keys is returned. Otherwise `true` is returned on success, or `false` on failure.

### Beispiele

Beispiel #1 A apcu_delete() example

`<?php
$bar = 'BAR';
apcu_store('foo', $bar);
apcu_delete('foo');
// this is obviously useless in this form
// Alternatively delete multiple keys.
apcu_delete(['foo', 'bar', 'baz']);
// Or use an Iterator with a regular expression.
apcu_delete(new APCUIterator('#^myprefix_#'));
?>`
